More from Deadline

Mantis is set in the same contract killer world as Kill Boksoon, which premiered at the Berlinale last year. While Kill Boksoon explores the story of Gil Bok-soon struggling to balance her life as a single mother and assassin, Mantis shifts the spotlight to other contract killers, named Mantis, Jae-yi and Dok-go.

Yim will play the role of Han-ul, an ace assassin also known as “Mantis,” working for MK Ent. The character Mantis was briefly mentioned by Kill Boksoon‘s Cha Min-kyu to “have gone on a vacation,” and this spinoff will trace Mantis’ return to the industry in search of new opportunities.

Upon Mantis’ return, he encounters fellow trainee Jae-yi (played by Park). Jae-yi is also Mantis’ old friend and she harbors complex feelings for him. Mantis also crosses paths with Dok-go (played by Jo), a retired legendary killer who is the founding member of MK Ent. Although Dok-go has long retired from active duty, he steps in as the CEO of MK Ent. after Cha Min-kyu’s death and hopes to bring Mantis back.

Mantis will be the debut feature of Lee Tae-sung, who co-wrote the script with Kill Boksoon director Byun Sung-hyun. Lee was an assistant director on Kill Boksoon and The King.

Mantis is produced by SEE AT Film Co., LTD, the company behind Kill Boksoon, Love and Leashes, and Kingmaker.
